Data model
In this section:
One of the characteristics of the RH850 microcontroller is a trade-off in how memory is accessed, ranging from cheap access to small memory areas, up to more expensive access methods that can access any location.
In the compiler, you can set a default memory access method by selecting a data model. These data models are supported:
The Small data model uses brel memory for storing data.
The Medium data model uses brel23 memory for storing data.
The Large data model uses huge memory for storing data.
All data models are available with or without support for short addressing. Data storage covers data models in greater detail and how to override the default access method for individual variables.
